Alright, so here's my problem with the tiles. I've put about 30 of my slate 400x400x10mm tiles on already around my shower area.
However, I've found today that 6 of them that I stuck on earlier this week aren't properly stuck to the wall. They seemed fine when I stuck them on I think, but now they sound hollower at the top edge and can be seen to flex very slightly when pushed at the top. The bottoms feel as solid as the other tiles.
I pulled one of them off today that I had applied yesterday and found it easily came straight off, with all the adhesive staying on the wall and none on the tile. As a test, I spread a thin layer of adhesive over the old adhesive and spread a thin layer on the tile too, then pushed the tile back on. Is this an ok thing to do? I'll see how well it's stuck tomorrow.
Here's my thoughts on what might be wrong:
1. Maybe the tiles were put up too late when the adhesive had lost stick? 4 of the faulty tiles were all done at the same time, so maybe I spent too long applying the adhesive that time? However, I only did 4 tiles at a time, mixing enough adhesive for 4 tiles each time in a clean container... and the other ones that don't seem stuck properly are all from different batches... so I don't understand how this could happen.
2. Maybe the tiles have a thin layer of quarry dust on their keyed back? However, nothing seems to come off when I wipe my hand across the back.
3. Maybe the adhesive I was sold is out of date? It says 28.05.09 on the pack, but that might be the date the batch was made which would mean it would be good for a year after, or maybe it's not even a date or relates to something else.
4. Maybe I should be back buttering the tiles? I'm pretty sure I wasn't told to do so in the supplier's instructions. I back buttered the row of 4 tiles I did today to see if it helps.
5. Maybe I squished these tiles too much such that they lost contact with the adhesive? I was pressing them all over and in corners to get them level with neighbouring tiles, maybe I shouldn't've done that? However, then wouldn't the tile that I took off have had some adhesive attached where contact hadn't been lost?
The tiles are Kirkstone Rio Neblina Cleft and the adhesive is the PCI Tilefast 6 Flex that they sell to go with them.
Some advice would really be appreciated, I've spent so long on this that I'll be devastated if I mess up the tiling... the tiles cost me £500... :helpsmilie:
